Today's Tech: Specs, release details and hands-on with Apple's iPhone 5S and 5C and the end of Android on Samsung smartphones?

Samsung could be getting closer to diminishing its reliance on Android, with screenshots showing a Galaxy S4 running a new version of the Tizen OS. Tizen Indonesia carries a number of photos that show the user interface [UI] of Tizen 3.0 on the Galaxy S4, suggesting the South Korean firm is seriously considering moving its devices over to the OS. Tizen is a Linux-based operating system that is the run by a Technical Steering Group made up of Samsung and Intel. The former merged its Bada OS project into Tizen with Intel doing the same with some of its MeeGo work. Samsung brought a Tizen based smartphone to the Mobile World Congress earlier this year.

UK spy agency GCHQ has just launched a new initiative aimed at trying to discover the next generation of cyber-security experts. Hopefuls can enter the 'Can You Find It?' competition through the dedicated website, where they will be confronted by a series of cryptic codes and puzzles. Successful applicants could win a Google Nexus 7 tablet, a Raspberry Pi, and even the opportunity to take up a job at the Government Communications Headquarters. A range of new vacancies will be on offer to applicants that make the cut, with salaries ranging between £26,000 and £60,000. "It's a puzzle but it's also a serious test – the jobs on offer here are vital to protecting national security," said Jane Jones, head of resourcing at GCHQ.

Intel has introduced the 22-nanometer Xeon E5 2600 v2 product family of processors for servers, storage, and networking infrastructure, promising up to a 50 per cent uptick in performance and a 45 per cent gain in energy efficiency compared with the preceding generation of Xeon E5 chips. The next-generation processors have set 15 new dual-socket performance world records across benchmarking tests that measure computing performance in areas like running databases, enterprise computing, web services, technical computing, virtualisation, and energy efficiency, said Diane Bryant, senior vice president and general manager of Intel's Datacenter and Connected Systems Group.
